摘要：

Synthetic aperture radar (SAR) has a distinct advantage over optical remote sensing due to its ability to map forest stock volume (FSV) relatively accurately in complex forests, while being less affected by weather conditions. However, significant discrepancies persist in the estimated FSV when comparing results derived from multiple dual-polarization SAR images acquired within a short time frame. This inconsistency severely limits the reliability and validity of FSV mapping. To investigate the influence of meteorological factors on FSV mapping accuracy, we collected 30 dual-polarization SAR i...
